ASHLY KLR-5000 Power Amplifier 2 x (2, 500W @ 2) (1, 700W @ 4) (1, 000W @ 8) Ohms

Product Overview

The Ashly KLR-5000 is a high-power 2-channel Class-H commercial amplifier delivering 2,500W per channel at 2 ohms, 1,700W at 4 ohms, and 1,000W at 8 ohms, with a 5,000W bridged mono rating at 4 ohms. As the flagship model of the Ashly KLR high-performance amplifier series, the KLR-5000 is engineered for demanding installed sound and live sound applications including line arrays, high-output speaker systems, and dual 18-inch subwoofer configurations. The KLR-5000 combines high sustained output power with a signal-to-noise ratio exceeding 110 dB in a lightweight 2U rack-mount enclosure, making it a practical choice for commercial AV installations where performance-per-rack-unit matters.

Product Description

The Ashly KLR high-commercial amplifier series delivers high levels of sustained power in a 2U enclosure that is exceptionally lightweight for its output class. The KLR-5000 uses a 2-step Class-H output topology paired with a switch-mode power supply, enabling the amplifier to run efficiently even at continuous high-demand levels. Front-panel controls include per-channel attenuators, a 3-position gain switch, a 3-position mode switch for stereo, bridged mono, or parallel mono operation, and a 3-position 12 dB/octave high-pass filter switchable between 30 Hz, 50 Hz, and off. An on/off limiter switch provides additional output protection. Inputs are balanced via combo XLR/TRS connectors plus 3-pin Euroblock; outputs use Neutrik speakON connectors for secure load connections. Cooling is front-to-rear forced air with removable, cleanable dust filters, making the KLR-5000 suitable for both touring and permanent rack installations. Front handles are removable for clean permanent installs. Optional locking knobs (KLR-LK2) are available for secure installations requiring front-panel tamper resistance. The KLR-5000 is TAA compliant and carries cCSAus, CE, FCC, and RoHS certifications, meeting the compliance requirements for government and institutional procurement.

Key Features

Technical Specifications

Frequently Asked Questions

What is the bridged mono power output of the KLR-5000?

The KLR-5000 delivers 5,000W bridged mono into a 4-ohm load, making it suitable for high-output single-channel applications such as dedicated subwoofer amplification.

Does the KLR-5000 support 70V constant-voltage distribution?

No. The KLR-5000 does not support 70V or 100V constant-voltage operation. For 70V distributed audio in the KLR series, the KLR-3200 is the appropriate model.

What output connectors does the KLR-5000 use?

The KLR-5000 uses Neutrik speakON locking output connectors, which prevent accidental disconnection in both touring and installed rack environments.

Is the KLR-5000 suitable for permanent installation?

Yes. Front handles are removable for a flush panel appearance, optional locking knobs (KLR-LK2) prevent unauthorized front-panel adjustments, and the amplifier is TAA compliant for institutional procurement.

What protection circuitry does the KLR-5000 include?

The KLR-5000 includes a switch-mode power supply with extensive protection circuitry, an on/off limiter switch, and thermal management via front-to-rear forced-air cooling with removable dust filters.

What input options are available?

The KLR-5000 accepts balanced inputs via combo XLR/TRS connectors and 3-pin Euroblock connectors, accommodating both touring-style XLR cabling and installation-style Euroblock terminations.
